AXLE=LUBRICATR.

SPECFICATION forming part of Letters Patent No. 392,906, dated November 131 1888,

Application filed May 17, 1888. Serial No. 274,179., (No model.)

To @ZZ whom it may concern.-

lBe it known that I, NVARREN COLE, Jr., a citizen of the United States, residing` at Knoxville, in the county of Knox and Stat-e of Tennessee, have invented certain new and useful Improvements in AXle-Lubricators5 and I do hereby declare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to that class of axlelubricators in which a grease tube passes through the hubs of wheels, in combination with a plug or plunger for forcing the grease down upon the axle while the wheels are on. Heretofore great annoyance has been experi enced in losing the plugs from theirplaces by constant jarring and droppings from the wheels; and the object of my invention is to overcome these obstacles by devising means whereby the plunger will always be securely locked in position and the locking mechanism shielded from injury, and a further object being to construct the plunger-handle in such a manner that it will combine strength and durability and can be manipulated with greater facility.

With these ends in View my invention consists in the mechanism more fully described hereinafter, and pointed out in the claims.

.Referring to the accompanying drawings, Figure l represents aside elevation 0f my complete device, partly in cross-section; Fig. 2, a rear end view of a hub to which my device is applied, and Fig. 3 a detail view of the tube.

The reference-letter a indicates an ordinary wagon-hub provided with a metallic box, b. The grease-tube cpasses through the hub at a point between the rear end and the spokes, and its exterior surface is smooth, except the lower part, which is provided with a sufcient number of threads, d, to engage with the threaded aperture c in box b. Then the tube is in place, the upper extremity is flush with the outer surface of the hub. An internal rabbet, f, is also provided for the reception of the shoulder g upon the upper part of the plunger. In order to facilitate the insertion of the tube, a pair of recesses, h, are made in its upper edge, which are located diametrically opposite each other to receive a screw-driver The plunger is provided hook, Z, is inserted in one ofthe spokes, upon the inside, a short distance above the hub, and engages the free end of the handle when the same is pressed forward against the resistance of the spring.

As an extra precaution against accidental displacement, and also to more rigidly and securely hold the plunger in place, I provide a lug, m, which consists of a piece of tlat metal attached by screws a to the rear face of the spoke. The upper surface of this lug is beveled off to allow the handle to slide down over it when 'the plungeris being inserted, and it projects beyond the side of the spoke and ata distance above the hub suflicient to allow the handle to be locked under it. The lower surface of the handle bears upon the top of the hub-band, which serves as a i'ulcrum when the handle is locked or being locked in position. The handle is so constructed that the springcoil and free end will lie between the spokes and be shielded by them.

In operating my device grease is lirst inserted in the lubricant-receptacle c and forced down by the plunger. Then the plunger has been forced home, it is given a slight turn laterally to bring the handle t between the locking-lug and hub-band. The free endK ofthe handle is then sprung forward and put in e11- gagement with the catch upon the spoke, or when the modification shown in dotted lines is used the hooked end o' is made to engage with thc inner edge of the spoke. When thus locked, the plunger will be securely held in place against any possible displacement from the rotation of the wheel or the usual causes. As the handle is made of a round bar of iron, any mud or droppings which may collect upon it can be easily removed by jarring it against.

a solid substance.

It is evident that my invention could be varied in numerous ways which might suggest IOO themselves to a skilled mechanic. Therefore I do not limit myself to the precise construction shown, but feel entitled to all such variations as come within the scope of my device.

Having thus described my invention,what I claim as new, and desire to secure by Letters Patent, is-

l. In an aXle-lnbricator, a lubricant-receptacle, in combination with a plunger provided with a handle extending between the spokes, in the manner and for the purpose substantially as described.

2. In an aXle-lubricator, a lnbricantreceptacle, in combination with aplnnger provided with a spring handle, substantially as described.

3. In an'axlelubricator, a lubricant-recep` tacle, in combination with a plunger provided with a laterally-extending handle having a coil-spring, substantially as described.

4. In an axle-lubricator, a lubricant-receptacle inserted in the hub between the spokes and rim, in combination with a plunger pro` vided with a handle extending laterally betweenthe spokes aud being locked in plaeeby a catch located upon one of the spokes, substantially as described. Y

5. In an axle-lubricator, a lubricant-recep taele, in combination with a plunger provided with a handle having a spring-coil located be tween the plunger and free end of the handle, substantially as described.

6. In an aXle-lubricator, a lubricant-recep tacle provided with a plunger having a laterally-extending handle and free end extending 35 substantially at right angles to the body portion of the handle,in combination with a catch, as specified.

V7. In an axle-lubricator, a lubricant-receptacle inserted in the hub of the wheel, in conibination with aplungcr having ahandlein engagement with one of the Wheel-spokes,where by the plunger is retained in place, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.
